Halloween costumes are something of balancing act—while you don’t want to be that girl who is too overtly sexy, you also don’t necessarily want to be the one in some over-the-top comedic getup that’s too cumbersome to use the bathroom. Year after year we’ll take costume inspo wherever we can get it—even if that means liberally modifying someone else’s idea—and we find pouring through photo after photo on the web inevitably jogs our creativity to produce a look we’re stoked to wear come Halloween night. Ahead, a cute crop of past getups from celebrities and It girls because if it’s suitable for this crew, it’s good enough for the rest of us, no?
